#1430: Buffer overrun in vector/diglib dig__fread_port_L with big-endian
negative
values on LP64 systems
---------------------------------------------+------------------------------
Reporter: rroliver | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone:
Component: Vector | Version: svn-trunk
Keywords: diglib portable LP64 big-endian | Platform: Unspecified
Cpu: All |
---------------------------------------------+------------------------------
The code in dig__fread_port_L is broken for handling big endian negative
numbers on systems where sizeof(long) != PORT_LONG.
Presently the code fails to negate the value and will write 4 bytes past
the end of the buffer.
Problem exists for all grass versions through to trunk...
Patch attached (patch against 6.4.1)
